The Terrain Poll returns the total pathloss in dB between the speciﬁed radios, and provides a two-

dimensional cross-section diagram of the intervening terrain proﬁle:

Note that the pathloss presented in RMS (in dB) is derived directly from the pathloss factor that

would be inserted in the DACS’ terrain query PDU. The pathloss shown in RMS does not

include any ranging effects (performed internally by the DACS), and thus does not represent the

full signal degradation experienced between the transmitter and receiver.
